(1) Spring (2) Throttle stop adjustment screw (3) Low idle adjustment screw (4) Load stop adjustment screw
Adjust the speed on the calibration bench to the "LOAD STOP ADJ" rpm that is specified in the TMI. Adjust load stop adjustment screw (4) to the output dimension that is specified in the TMI.
Tighten the locknut for load stop adjustment screw (4) and check the output dimension again.
Increase the speed on the calibration bench by at least 100 rpm. Reduce the speed on the calibration bench back to the "LOAD STOP ADJ" rpm that is specified in the TMI. Check the output dimension again.If the dimension is not within the "RECHECK TOL" that is specified in the TMI, repeat Step 10.
Adjust the speed on the calibration bench to the "FUNC CHECK #1" rpm that is specified in the TMI. The output dimension must be a maximum of 0.0 mm (0.00 inch).
Adjust the speed on the calibration bench to the "THROT STOP ADJ" rpm that is specified in the TMI. Adjust throttle stop adjustment screw (2) in order to obtain the output dimension for the "THROT STOP ADJ". Tighten the locknut for throttle stop adjustment screw (2) and check the output dimension again.
Increase the speed on the calibration bench by a minimum of 100 rpm. Then reduce the speed back to the original "THROT STOP ADJ" rpm. Check the output dimension again. If the output dimension is not within the specification that is specified in the TMI, repeat Step 14.
Adjust the speed on the calibration bench to the "FUNC CHECK #2" rpm that is specified in the TMI. The output dimension must be within specifications. If the output dimension is not within specifications, repeat steps 10 through 16.
Adjust the speed on the calibration bench to the "FUNC CHECK #3" rpm that is specified in the TMI. The output dimension must be within specifications. If the output dimension is not within specifications, inspect the torque cam for wear or damage. Make sure that the correct torque cam is installed on the governor. If the torque cam needs to be replaced, refer to the Disassembly and Assembly, "Governor (Type) - Disassemble" and Disassembly and Assembly, "Governor (Type) - Assemble" sections in this manual.Note: If the governor is not equipped with a fuel ratio control, proceed to Step 21. If the governor is equipped with a fuel ratio control, continue with Step 18.

(7) Fuel ratio control adjustment screw
If the governor is equipped with a fuel ratio control, purge the air pressure to the fuel ratio control. Adjust the speed on the calibration bench to the "FRC ADJ" rpm that is specified in the TMI. Adjust fuel ratio control adjustment screw (7) in order to obtain the dimension that is specified. Tighten the locknut for fuel ratio control adjustment screw (7) .
A regulated air supply of 140 to 210 kPa (20 to 30 psi) must be used to avoid damage to the fuel ratio control.
Apply regulated air pressure to the fuel ratio control
